.TOUR/NAL BOX FOR CAR VJHEELS.

Application filed Septeinberll), 1926. Serial No. 134,626.

My invention relates to journal boxes for Vcar wheels and moreparticularly to journal boxes adapted for the support of roller bearingsand which may be readily removed from the axle when desired.

Heretofore, Vjournal boxes 'have been constructed in two parteconsisting of a top plate and a barrel within which a roller bearing issupported. The top plate is adapted to 'be secured to a car sill and toact as a hanger for the support of the barrel. The barrel'and top plateare so constructed that the barrel maybe slid into engagement with thetop plate and is retained between an `4 abutment formed on thetop plateand the ear wheel.

Journal boxes of the type referred to and to which my invention pertainsare adaptable to both lixed and loose wheels and may be removed fromvthe axle. However, such lboxes are open to a number of objections,

chief among which is that while such boxes are removable they are not,under all circumstances, readily removable and as constructed requirefor their removal displacement of the top plate or hanger in allcircumstances.

Now` yit is the object oii'my invention to provide a journal box or" thetype indicated, which will possess all the advantages ofsuch boxes asheretofore constructed and in addif tion thereto will be readilyremovable from the axle inallcircumstances and without displacement ofthe top plate or hanger from which it is supported.

Having now indicated, in a general way the nature and purpose of myinvention, I

' will proceed to a detailed description thereof with reference to theaccompanying drawings in which there, are shown preferred em.

bodiments of my invention and in which Fig. l is a plan view, partlybroken away, ofl a journal box embodying my invention.

Fig. 2 is an end view of the subject of Figure l.

F ig. 3 is a sectional view on line 3 3 Figure 2. j

4 is sectional view on line` 4 4 Figure 2.

F ig. 5 is an end view of a journal box embodying a modification of myinvention,

Fig. 6 is an invert-ed plan view et the subject of Figure 5.

Referring more particularly to FiguresV 1 4, in which there isillustrated aV journal box assembly involving my invention, L mdicatesthe base portion of a top plate,l or

outer face of thesill, as is clearly shown in Figure l.

The top plate, or hanger, is provided, beneath the base portion, withdownwardly and inwardly extending flanges, which form sl'ideways. Theportion of the base which extends beyond the outer face of the sill isdrilled, at points above the end portions of the slit eways formed bythe flanges (Z, for the passage of bolts e, which act to block the endsof the slideways and the end portions of which protrude through suitableholes drilled in the inturned portions of the {lang-ges (Z. The boltsmay be heldin place by means of cotter pins f.

The barrel, or journal box g is formed, in the embodiment illustrated,to receive a roller bearing, which is entered in the barrel and retainedtherein against an internal web z', by means of an end cap jsecured to aflange la at one end of the barrel, by means of rivets Z. The end of thebarrel opposite to that closed by cap j is permanently closed by an endwall m provided with an oil hole oz, which forms an oil reservoir withthe internal web i. The web i and end cap j are provided with openingsfor the passage of the end portion of an axle o upon which is mounted awheel p.

The barrel, or box, is provided on its top with aV rounded pad 71, andadjacent its top with oppositely extending flanges g adapted to enterthe slideways formed by flanges CZ depending from the base portion ofthe top plate or hanger.

In practice assuming the top plate, or hanger, to be secured to a carsill, as indicated in Figure l, and the bolts e removed, the car issupported, as by a jack, at the proper height and the axle o ispositioned beneath the hanger. rlhe box g is then slid on the end of theaxle until the flanges g are within the slideways in the hanger. Thebolts e are then put in place. As will be now observed, after the boltsare put in place, the box cannot be withdrawn from the hanger and itwill be prevented from passing through the hanger by the `Wheel p,against the hub of which the end of the box will contact before theflanges Q can leave the slideways.

The slideWays are so proportioned and the pins e so positioned withreference to the Wheel p that the box Vwill have substantial movement onpad 7L., which will bear beneath the base portion @,'in order to permitautomaticalignment of the bearing.

Referring now more particularly to Figures and G, in which there isillustrated a modified embodiment of my invention,

cv indicates the base portion of a top plate vor hanger, provided withbosses c and adapted to be secured beneath a car sill, vby means ofbolts passing through suitable holes drilled in, thebase portionandbosses.

Beneath the top plate depends aflange r, which forms a quadrilateralrecess, closed adjacent one endf as shoivn at s, Figures 5 and 6.Adjacent the other end of the recess the flange fr is drilled'for thepassage of a bolt t, which may be retained by means ofa cotter pin/i.The barrel or journal box u, having a rounded pady it on its top, ispreferably cylindrical and adapted for the reception of Y a rollerbearing Within which the end portion of an axle of, upon which ismounted a Wheel ya', is` adapted to extend. The box vet has formed on itlaterally extending wings or flanges o, one of which is adapted to beextendedv Within the closed end of the recess formed by the flange rand. the,v other of which is adapted to be retained Within the recess bymeans of bolt t.

In practice, assuming'- the hangeror top platel to be secured' to theoar sill, the barrecess 'and the bolt t put in place.

rel or journal box is slipped on the end portion of the axle 0 andtipped to enter one ofthe Wings or flanges o Within the closed end oftherecess formed by flange r. The other Wing or flange u is Vbrought intothe As Will be noted, the bolt t passes beneath the Wing a and acts toretain the boXvin engagement with, the hanger; further the box iscapable of substantial movement about pad h permitting automaticalignment of the bearing.
